I have a 2010 Nissan Versa 1.6 base manual transmission which refuse to start one morning. I figured it was the battery and replaced it, but after I did the car still would not start. None of the lights would even come on, headlights dash lights dome lights but the red security light on the dash keep flashing no matter what. After reinstalling the battery a second time the radio came on even when the he was out of the ignition. I did some Googling and found there were three bolts to tighten which must have had a screw loose to the ground which cause the radio to stay on which could have drain the battery in the first place. After tightening that I reconnected the battery but could not Resync the key. I tried several times leaving the battery terminal off for several hours, but nothing worked. I noticed once that if I touched the battery terminal to the post a couple of times I could get the dome light to come on like it's supposed to. I tried to resync the key but it just goes back to the security state. Does anyone have any suggestions?
